Well, I think my title states what the problem is.

DontDestroyOnLoad(); is pointless to use, because "bs" objects are different in the scenes, and AD Initialization should be called once. I get no error in the console. Initialization works as expected. In summary, everything works as it should, when I enter the new scene Initialization works as expected but when I click the button for reward nothing happens. The same happens after Reloading the scene.

What should I do next?
